' oonsrnarion-roon To all whom it may concern v Be'it known that m J: JoHNsoN, aycitizen offthe, United-States,,.-residing at Dulutlnjin the-county of Louis and State of Minnesota, have invented. certain new and useful Improvements in Gombination" Tools, of which the following is a specifica- .tion, reference being. had there n to the accompanying drawing. This invention relates to wrenches and has special reference to a novel form of comi as a pair of pliers or a wrench, but also as s Figure 1 is a central sectional View of the I combination lnstrument;

I Fig. 2 is a side elevation of same; and Fig. '3 is a transverse sectional view on the line 33, Fig. 1.

The main body portion of the tool comprises the shank 1 and handle 2, which are of a single piece; and upon the outer end of the shank 1, formed integral therein, is

the fixed jaw 3 of the wrench. The jaw edge of the shank 1 has formed therein alongitudinally disposed rectangularly shaped channel, the same passing through the base of the aw 3, and into which channel is SllClably mounted the cogged rack 4' which normally extends towards the. jaw end of the wrench the full lengthof the channel,- and upon such end is provided. with an enlarged head 5 having a notch or recess 6 formed in the face thereof away from the aw 3. Into this notch 1s cooperatlvely engaged a lug or cog 7 which is an integral part of the head 8 of the arm Qwhich is pivotally mounted at 10 in 'the bifurcated extension 11 or the head of the shank 1. Thuswhenthearm 9 is raised or loweredon its pivotal point 10,

the rack 4 will be reciprocated backand forth as is obvious.

' The arm 9 provided with a handle-like em'nsien 1.2 paraiieiwa fale We portion 20f thewrench, andwhich completes said handle portionand. is so shaped asto operator.-

1 1 Intermediate of theends the and handle, 3-12 is an integrally formed proectlon 13 which extends at practically right angles tothe main portion ofthe. arm so that. the. latter may be closed into a suitably formed open ng or aperture through. the

nainbody portion 1 .;2 ofthe wrench. The channel in whichthe'rack reciprocates ,ter-

minates in the lower end of the aperture, so

that when the arm 912 is in its closed position against the main body portion of the wrench and the rack 4 fully extended outwardly, the projection or key 13 will fill the aperture in the main body portion and act as a stop for the inner end of the rack 4 which will impinge against same during such time as the wrench is being employed in engag make, a convenient grip for thelhand of the ing an object either as a wrench or when the jaws thereofare' tightly impinged against the object. A second adjustable jaw 14, suchas are common to similar wrenches, is reciprocally carried upon the shank 1 of the wrench and has rotatably mounted therein a short worm 15 on the pin 16 and which worm meshes with the teeth on the rack 4 and by rotating the worm 15 any. desired variation in the space intermediate of the aws 3 and 14.- may be accomplished, as is common to such devices. H

By this arrangement it will be seen that when it is desired to tightly engage for examplea} nut in either tightening or loosening same, the jaw 14 may be adjusted to approximately the proper size of the nut,'when the handle 12 is separated from'the handle portion 2 of the wrench, then when the wrench is applied to the nut and the two parts 2 operators hand, a pinching of the nut will result which is impossible to accomplish with a common wrench. I

While I have explained how a common nut may be thus forcibly grasped, it is evident thatin the turning of many small objects like rods or pipes the same forcible pinching may be accomplished,which will result in a veryefiicient wrench, and by the provision of the key 13 back at the reciprocal rack; 41 the efficiency of the implement when used as a common Wrench is in no wise impaired. I

, thus when closed they will hold the object I have illustrated at 17 and 18 two outaway portions in the cooperative jaws 3and 14 which would result in the jaws being provided with common wire cutters; and it is apparent that in such case when the jaws 3 and 14 are adjusted by the worm 15 to impinge the wire to becut and the handles 2 and 12 brought forcibly together an ideal cutting effect would result. 7

When the instrument is used as a vise, the

jaws are drawn up as before to impinge the object when the pincer handles are opened,

firmly; and I have provided a pivotally suspended link 19 loosely hung in the extreme free end of the handle 12, which may be dropped down overthe extreme end of the handlee and snapped into the recess-2O in said handle, where it Will firmly hold the I two together and the jaws thus permanently hold the object. I

Having thus described my invention, what I claim and desire to secure by Letters Patent,is: A V

1. A wrench comprising in combination a main body portion having a fixed j aw upon one end thereof, aslidable jaw carried by the body portion, slidable means intermediate of the two jaws, separable therefrom and coactively uniting the same, and an arm-i ciprocal movement of the'movable 'jaw in 40 one direction. V

In testimony whereof I hereunto afliXmy signature in the presence of two witnesses.
